The significance of freehand drawing in the teaching process in general construction project classes
Get PDFAs you know, the first requirement faced by the candidate wishing to study at the Faculty of Architecture is freehand drawing; passing the examination in it is the basis for admission. Freehand drawing in both the teaching process, and then in the professional activity is an expression of artistic and spatial sensitivity of every student and architect. It also has a high priority in the design process, especially at the stage of an idea, concept and architectural creation. Before there appeared the possibility of using the computer, concepts and student projects had been performed manually during the teaching of all design subjects. It was a rule to prepare designs in pencil techniques, in ink, and other tools and techniques ‒ e.g. watercolor, tempera, feather, etc. The creative process required understanding and analysis of the developed vision or architectural issue in the context of brain ‒ eye ‒ hand relations. In the era of universal computerization these relations and correlations have been weakened, which, as can be seen in practice, does not always produce good ‒ expected ‒ results in the teaching process. First of all, probably, due to the deterioration of the function of imagination (including aesthetic one) among entrants and the strengthening of their tendency to laziness (including taking “shortcuts”), which in a sense is ‒ for artistic professions ‒ even murderous. Therefore, observing messages of creativity among students of architecture, one can state that the computer can, of course, be an aid, but it cannot be the main tool in mental, emotional and creative development process
Gametecture: architectural form in augmented reality
Get PDFArchitectural forms of the digital age are based on games and computer simulations: formation, information, transformation. Formation means creation of structures as extensions of the kinetic potential of the human body (form as skin or wrapper). inFormation is based on the active power of information (interactive and intelligent structures). transFormation means sequences of forms as mutations of primary structures in topological space (metamorphic forms)
Light in architecture – architecture in light
Get PDFIn December 2013 the 68th Meeting of the United N ations named 2015 The International Year of Light-Based Technologies. This fact was to focus the world’s population on the importance of light technology in promoting balanced progress. I n this context, the omnipresent use of light in architecture (the inner and outer buildings space) requires analysis and revision
Efficient methods for synthesis of florol and its derivatives
Get PDFThe paper describes and compares the two methods of synthesis of florol (1) (4-methyl-2-(2-methylpropyl) tetrahydro-2H-pyran-4-ol) by the Prins reaction. The first method involves the reaction for obtaining 1 in methylene chloride as solvent at 60°C. The second method applies the preparation of florol (1) and other tetrahydrofuran derivatives in solvent-free conditions in room temperature
Threats to historic parks arising from the conflict of cultural and natural values
Get PDFThe values which dictate whether a historic park is listed as a heritage site, and which justify the need for statutory protection, are its historical, artistic and scientific values. The lack of public understanding and respect for these values, and the failure to perceive historic parks as works of garden art, and not merely as biologically active areas used primarily as recreation sites, poses many serious threats to this group of heritage sites
Architect’s free hand drawing as a form of presenting the art of space shaping as illustrated by the example of the author’s profession
Get PDFWhat was and still is free hand drawing as an architect’s tool for conveying the vision of an object, presenting the concept of creating, shaping the balance between the constructive matter and the creative abilities of the maker? Drawing serves as a presentation of an idea. The architect’s draught is the result of a dialogue between thought, hand and an idea. Creating without emotion is not art. Drawing is only a form of recording. It is an endless act of perfecting the author’s work. This text presents the main stages of development, examples of artistic narration, which is an alternative to the individual form of constructing conceptions of space and its critical factors. This article aims to explain the relations between life and art, which are analysed through two similar problems: how to successfully influence the investor’s senses through the use of the drawing art. The author (through presenting the rank of drawing in his profession) aims to prove, that the architect’s freehand drawing stimulates imagination, sensitivity, spirituals values, traditional aesthetics. It emphasizes colour, rhythm, order and dynamism. A work doesn’t have to be created in the virtual world to become the full interaction between the inner and outer factors. The architect’s freehand drawing reflects the unconstrained creation of the mind concerning the status of the form in space as an artistic event
Experimental Study to Develop a Control System for Submersible Mixers in Biogas Plants
Get PDFFor developing a control system for these agitators, the analysis focused on the rheological characteristics of digestates, the open jet in non-Newtonian fluids and the flow conditions in a biogas reactor. In addition to a clearly visible shear-thinning effect, the viscoelastic proportion of these substrates was also determined. Depending on the stirrer speed and the rheology, the angle of spread varies and a reverse flow can occur directly at the stirrer. Therefore, not only can the position of the stirrer be used to optimise the flow field. The conical spreading of the liquid jet also enhance the mixing process. By using thrust measurements, their suitability as controlled process variables could be demonstrated
Management of the innovation project in the area of design and implementation of microprocessor systems for the railways
No full textIn the paper, the main elements of the management of product innovation projects in the field of microprocessor systems for the railway industry are identified. The advantages and drawbacks of methods, tools and techniques used for the management of innovation projects are discussed. Also, their influence on efficiency, quality, safety and effectiveness of the management of this kind of projects is described. Based on the available literature sources, contemporary tools and technology means enabling development of safe (from the functional point of view) microprocessor systems as well as the significance and influence of formal and legal factors on the way of projects execution are presented. The conducted analyses result in recommendations for necessary changes and improvements of the execution phase and identification of key success and threat factors in the management of innovation projects for the railways
Ludwik Silberstein and the operator calculus
Get PDFIn the article we outline the life of Ludwik Silberstein (1872‒1948). We present his approach to the matrix calculus and its application to the operator form of relativity. We also give the list of books on the subject written by him as well as translated by him
Play towers, game of halls
Get PDFThe issue is playful, so my choice was to develop it by comparing two highly contemporary themes and absolutely classical types in architecture: the Type Tower and the Type Hall. I nstead of writing to describe concepts and thought, I prefer to show my drawings and designs exploring figures and meanings, memories and experiences
